While other films about ballet have gone for big-name actors with body doubles for the dancing bits — think of “Red Sparrow” and “Black Swan” — Fiennes was committed to casting a dancer as Nureyev. Yet the dancing scenes, he says, “were a big, big, big challenge, because I don’t have a ballet background, and I needed the help of the ballet masters and choreographer to know if it was good, because not every time a dancer dances it’s as good as it could be. It was scary.” – Washington Post
